a group of 13 girls ranging between 13-17 years of age. formed in august 2012 on twitter, they are known for constantly starting twitter fights, or "beef". though they come off as hostile, they're fiercely loyal to each other and others outside of the group. they are very exclusive, so just asking to join their group comes off as naive and a tad idiotic. all in all, they are either very respected or very looked down upon, but they still continue doing their own
"Bro, did you see that beef on twitter last night? So many people got blocked!"
"Dang, I missed it! I was too busy watching Bates Motel! Who was involved?"
"The Backer Street Bitches, it got hecka intense!"
"Typical, right? Haha!"
